T0 all whom it may concern.-

Be it known that I, GEORGE F. CRAMER, a citizen of the United States, residing at East Rutherford, in the county of Bergen and State of New Jersey, have invented certain new and useful Improvements in Metal Screens; and I do hereby declare the following to be a full,

clear, and exact description of the invention,

such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to figures of reference marked thereon, which form a part of this specification.

The objects of this invention are to provide an all-metal screen which will permit of arenewal of the netting with greater facility and ease and at a reduced cost of construction, to provide a screen with interchangeable parts which will be more simple in construction and compact, so as not to occupy much space in the window, and to obtain other advantages and results, some of which may be referred to hereinafter in connection with the description of the working parts.

The invention consists in the improved metal mosquito bar or screen and in the arrangements and combinations of parts of the same, all substantially as will be hereinafter set forth and finally embraced in the clauses of the claim.

Referring to the accompanying drawings, in which like numerals of reference indicate corresponding parts in each of the several figures, Figure 1 is a front elevation of my improved screen, a certain marginal casing being removed. Fig. 2 is an edge view of a portion of the same on an enlarged scale. Figs. 3 and 4: are sectional details illustrating the construction of the inner frames for clamping the edges of the netting. Fig. 5 is a detail plan, partly in section; and Fig. 6is asection of the same, taken at line 00, Fig. 5.

In said drawings, 7 indicates the wire-netting, and 8 and 9 the clamping members between which the said netting is secured, the said members being joined together by clamping-screws 10 or other suitable means. The clamping member 8 consists, preferably, of four corner parts 81, coupled together by overlapping side pieces 82. Each corner part comprises two sections arranged one at right angles to the other and united at the angle, the ends at the angle being flat Where the sections overlap. Said sections are riveted together, as at 11, and are slotted, as at 12, to

permit an adjustment of the said section with relation to the side pieces 82 when enlarging or reducing the frame to adapt it to the window-frame with which it is to be used. The said corner parts 81 and also the side parts 82 are V-shaped in cross-section to form a groove to receive the correspondingly- V- shaped clamping member or members 9. Said members 9 are perforated and threaded to receive screws 10, and when said members 'are laid together with the wire-netting between on screwing up said screws 10 said netting is bent to conform to the clamping members, and consequently is held in place with great firmness and security. The member 9 is preferably in four parts, each of which extends nearly from one angle to another, crossing the joints formed by the parts 81 82 and giving great stiffness to the frame, especially when it is of solid metal in crosssection, as distinguished from sheet metal. To cover the framework thus constructed and make it more presentable in appearance, I inclose the said framework in an outer casing 14, such as is shown in Figs. 5 and 6, where the said casing is shown to consist of four side pieces 15 and four corners 16, the said side pieces 15 entering at their opposite ends the corner-pieces 16, and thus having an adjustable relation whereby the size of the casing-frame can be increased or diminished to correspond with the interior frame. The said side pieces 15 are of sheet metal, which in cross-section is doubled, as at 18 18, to lie on opposite sides of the interior frame, forming a slot 17 through which the netting can project out from the interior, and the cornerpieces 16 are correspondingly slotted at their inner edges to permit the outpassage of the wire. The said corner-pieces are each provided with a clamping-screw 20, which enters through from one side of the corner-piece t0 the other, a threaded bur being formed on one of the sides to secure a stronger hold when the said screws are tightened up to their limit.

Having thus described the invention, what I claim as new is- 1. The improved window-screen herein described, comprising aninner frame consisting of clamping side parts and overlapping angular parts, netting clamped at its edges between said side parts, and a casing doubled over the inner frame and comprising side pieces and corner-pieces adjustable in relation to one another, substantially as set forth.

2. The improved window-screen hereindescribed, comprising an inner frame consisting of grooved clamping side parts and cooperating clamping parts fitting into said grooved parts, means for separably fastening said parts together, corner connections for said side parts,and netting held at its edges between said clamping parts, and an outer frame doubled over the inner frame and the edges of the netting, substantially as set forth.

3. The improved screen herein described, comprising an inner frame consisting of clamping members, a netting clamped at its edges by said members and an outer casing inclosing said inner frame and having a slot through which the netting extends, said casing consisting of corner-pieces and side pieces extending into'said corner-pieces.

4. The improved screen herein described, comprising a frame consisting of clamping members \I-shaped in cross-section, and comprising angular corner-pieces and side parts overlapping said corner parts.

5. The improved screen herein described,

comprising an inner frame having a grooved member and a member fitting into the groove, netting bent between said members and held in place thereby, and an outer casing inclosing said inner frames, substantially as set forth.

6. The improved screen herein described, comprising an inner frame having a member consisting of grooved angular parts and grooved side parts, and a member fitting the grooves of said parts and clamping-screws, a netting entered at its edges between said members and a casing doubled to cover the opposite sides of said frame, substantially as set forth. r

In testimony that I claim the foregoing I have hereunto set my hand this 22d day of 4 August, 1905.

GEORGE F. CRAMER.
